Recently ICQ published their official Linux client for 32- as well as for 64-bit machines.
Graphically it is the same client as for windows, which is pretty neat, unfortunately there is a small problem with the login – the widely known error “Error occurred, try again later”.
There is a very easy fix for it.
Just open your console/ terminal and type in the following:
sudo ln -s /etc/ssl/certs/ca-bundle.crt /etc/ssl/certs/ca-certificates.crt
